Area code 817 is a significant telephone area code in the North American Numbering Plan, serving areas in the state of Texas. Geographic Coverage: Area code 817 covers the city of Fort Worth and most of the western portion of the Dallas-Fort Worth metroplex. It serves all or parts of several counties, including Tarrant, Johnson, Parker, Hood, Wise, Dallas, and Denton. This makes it a crucial part of the telecommunication infrastructure in this densely populated and economically significant region of Texas​​. History and Origin: The area code was created in 1953, primarily from the split of area code 915, one of the original area codes established in 1947. This historical background reflects the evolving telecommunication needs in Texas over time. The area code 817 has been instrumental in serving a large and growing population in the Dallas-Fort Worth area​​​​. Largest City and Overlay Code: The largest city served by area code 817 is Fort Worth. Other significant cities within this area code include Arlington, Euless, Grapevine, and Roanoke. Additionally, area code 817 is overlaid by area code 682, allowing for a larger pool of phone numbers within the same geographic area. This overlay is a common practice in regions with high demand for new telephone numbers​​​​​​. Time Zone: Area code 817 is located in the Central Standard Time (CST) zone. Like most areas in the United States, it observes Daylight Saving Time, which involves adjusting the clocks forward in spring and backward in autumn to extend evening daylight during the warmer months​​. In summary, area code 817 is vital for telecommunications in the western portion of the Dallas-Fort Worth metroplex in Texas, encompassing several key cities and counties. Its establishment in 1953 and its overlay with area code 682 reflect the growing telecommunication needs in the region. The area code's location in the Central Time Zone and adherence to Daylight Saving Time are also significant operational aspects.
